HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 747,360, dated December 22, 1903.

Application filed September Z4, 1903. Serial No. 174.456. (No model.)

To @ZZ whom it may concern,-

Be it known that I, HARRY G. BARRY, 'a

citizen of the United States, residing at Ponduction, durable in use, and whose parts are'v adapted to couple perfectly water-tight and to be quickly and conveniently coupled and uncoupled.

In the accompanying drawings, Figure l is a longitudinal section of a hose-coupling embodying my invention, showing the parts or members coupled. Figs. 2 and 3 are detail perspective views of the members separated. Fig. 4 is a cross-section on line 4 i of Fig. 1, and Fig. 5 is a detail view of the releasingring. t

Referring now more particularly to the drawings, A and B represent two parts of a coupling,which may be secured to the meeting ends of hose-sections in any preferred way.

The coupling member A is tubular in form and is provided with a series of locking-jaws l, three of such jaws equidistantly arranged being shown in the present instance. Each jaw consists of a spring-metal strip extending longitudinally upon the outer side of the member A and secured at its inner end thereto by a suitable fastening 2. The outer or free end of the strip is provided with a locking projection 3, extending inwardly and adapted to move within an opening et in the section A. The resiliency ot' the spring-metal strip normally causes the projection 3 to extend through the opening 4 upon the interior of the member A. As shown, the openings 4 are disposed adjacent to the outer or coupling end of the member A and are formed in a reduced portion thereof, the wall of said member at the rear of said reduced portion being beveled off to forma contact-shoulder 5.

The member B of the coupling has a reduced end 6 to fit within the reduced portion of the member A, the extremity of which end 6 is shaped to form a beveled portion 7 ,which is adapted to engage and project the projections 3 of the dogs 1 and to abut against the beveled surface 5 to form a perfectly watertight connection when the members are coupled together. In rear of said Ybeveled surface 7 an annular groove 8 is formed in the part 6, and this groove forms a keeper which is designed to receive the projections 3 of the dogs to lock the coupling members together.

In the operation of the coupling the proximal ends of the sections A'and B are brought together and telescoped one within the other, and as the portion 6 of the member B enters the reduced portion of the member A the beveled surface 7 will engage and force out the projections 3 of the dogs 1, thus allowing said portion 7 to abut fully against the shoulder 5, whereupon the said projections 3 will snap into the keeper-groove 8, and thereby lock the coupling-sections together.

In order to release the coupled sections from engagement, I provide a releasing device, consisting of a ring 9, which is mounted to turn or oscillate in a groove lO in section A below the dogs 1 at a point just in yrear of the shoulder 5 and contiguous to the projections 3. This ring is tangentially recessed at equidistant points around its circumference to form alternate cam-shaped or inclined seats 1l 'and concentric peripheral portions l2, the latter being milled or roughened to give a securenger grip lto allow the ring to be conveniently turned or rotated. When the ring is so arranged that theseats or recesses 1l lie beneath the dogs l, the latter are permitted to move inwardly by their spring action to the fullest extent, so as to cause the projections 3 to extend through the openings4; but

when the ring is turned or rotated in the direction of ascension of the inclined walls of said seats 4or recesses the latter, actingin the nature of cams or eccentrics, will force the dogs outwardly, and thus retract the projections 3, so as to allowfthe members of the coupling to be disconnected. As shown in the present instance, the ring is composed of sections having lapping ends which are connected by screws or like fastenings 13, this.

construction facilitating the application of the ring to the groove l0; but this construction may be varied as desired.

' From the foregoing description, taken in connection with the accompanying drawings,

IOO

the construction and mode of operation of my hose-coupling will be readily understood, and it will be seen that it provides a couplingr device which is simple of construction, efficient for its intended purpose, adapted to form a Water-tight joint, and which by easy manipulation may be quickly and conveniently coupled and uncoupled.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my inventiou,what I claim, and desire to secure by Letters Patent, is

l. In a hose-coupling, in combination with a section having a keeper device, a section having a spring-dog to engage said keeper device, an annular groove crossed by said spring-dog, and a revoluble ring in said groove having a cam to bear under the spring-dog and move the same out of engagement with the keeper device upon a partial revolution of the ring.

2. In a hose-coupling, in combination with a section having a shouldered reduced end portion provided with a peripheral annular keeper-groove, a section having an internallyshouldered end portion to telescopically eugage the reduced end portion of the firstmentioned section, and being further provided with openings to register with the keeper-groove, longitudinal recesses communicating with said openings, and an annular, 'peripheral groove intersecting said recesses,

spring-dogs countersunk in said recesses, hav- HARRY G. BARRY.
